It's absolutely worth it...and then some.
It does depend a lot on how savvy you are with tech and computers, admittedly. But DO NOT use EFIX. EFIX uses the same base software modifications that TonyMac does, but they put it in an easy-to-use USB dongle that plugs straight into your motherboard. There was a huge hullabaloo here a while back about them selling software that is already free.
That, and it's "proprietary", so you can't update your computer if EFIX doesn't put out an update. I did it with the TonyMac method and never looked back. When the OS comes out with a point update, hit the forums and look for the official TonyMac announcement in the blog about how to safely upgrade.
I built my computer using the then-new Sandy Bridge CPU. It was so new, I was one of the "pioneers" trying to figure out the workarounds to get it to work (I bought the chip the day it was released). It was Hell. But that's because nobody knew how to work it. Now, you can skip that, as people have done the legwork for you.
My suggestion? Use Custom Beast. You buy the hardware, tell them what you have, and they build you a custom installer for that hardware specifically. Or check the CustoMacs for directions on how to build a Mac-equivalent Hackintosh. Want a Mac Mini? They have it listed. And part-for-part, the price difference will astonish you. At the base level Mac Pro you may save only a couple hundred by building it yourself, but if you want a higher-end Mac Pro, the savings of building it yourself becoming exponential. I built a $3000 mac for $1200. I used the extra cash to buy 3 monitors and an awesome 6-screen-capable graphics card.
Two screens horizontal for the PT Mix Window, two screens vertical for the Timeline, and one monster screen for the video. Do that on a standard Mac Pro...
And you can overclock and watercool a Hackintosh, so you can have a blazing-fast CPU for the most demanding sessions, and your water cooling makes your tower so quiet, you can leave it in the same room that you edit in. Do that on a standard Mac Pro...
Is it a lot of time spent? Depends. Possibly. Will you enjoy every moment of the result? YES! I slaved over my Workstation for 3 weeks trying to work out on the bugs on the new SandyBridge processor. But if I'd started building this thing just today, there are so many tutorials on how to do it, it would have taken me a day.
If you'd like help, I'd love to give you any advice or pointers on this. I'm a huge Hackintosh proponent (obviously).
